before:Today, I like to talk about the subjcet about geneic modication. We shoud't be so confused by biologoical with genenic modication which is a far more general term. In fact, biologics use   to make products and as examples to use enzm to make cheese or yorgut. Er, let's back to the main topic, let's establish the defination of the term of geneic modication. Anyone? Altering the structure of the genenic desin of a plant? That's partly right, but not just plants. It also refers to animals backteris, or any organism. The outcome of altering genetic names like genenic modifine, genenic engeneeri.
Now why do we want to alter the make up of the genenic of plants or animals? To make it grow faster? To make it to resist to diseaces? Yes, both of you are correct. Thoese are two important reasons. There're a number of another reasons too. Er, for example, to improve the cross ability to survive in the dry consitions. or add an important nutruit to people's dieat, or add something into the pill to debate one disease.
It's important to disscuss where this teqic takes us,  all organism alter their genenic to adpat to the envole. But for the first time, we have the tecqeic to control the process. Now the first and important step for this prcess is to identify the charecter of the genenic. And of course we also find new techknowledges to anylise the data.

after:

Today, I'd like to talk about the subject about genetic modification. By the way, we shouldn't confuse biotechnology with genetic modification, which is a far more general term. In fact, biotechnology refers to using of organisms to make products and includes for example, something as simple as using enzyme to make cheese or yogurt. Er, let's get back to the main topic, let's establish the definition of the term of genetic modification. Anyone? Altering the genetic structure of plants? That's partly right, but not just plants. It also refers to the genetic makeup of animals, bacteria, or any living organism. The result organism is said to be “genetic modified”, genetic engineered” or “transgenic”

Now why do we want to alter the genetic makeup of plants or animals? To make it grow faster?To make it be resistant to disease? Yes, both of you are correct. Those are two important reasons. There're a number of other reasons too. Er, for example, to improve the crops’ ability to survive in the dry conditions. or add an important nutrients to people's diet, or add something into the pill to debateone disease.

It's important to discuss where this  technology takes us,  all organism alter their genetic structures to survive. Now for the first time, we have the opportunity to control the process. Now the first and important step for this process is to identify the characteristics of the genetic. And of course we also find new technologies to analyze the data.

Today I want to talk about a  way in which we'are able to determin how old a piece of land or some other geological feature is-dating techniques,
I'm going to talk about particular dating technique, why?
Good dating is key to good analysis.
In other words, if you want to know how the land formation was form, the first thing you probably want to know is how old it is, it's fundamental.
Take the Grand Canyon, for instance.
Now, we geologist thought that we had a great idea of how the grand canyon and south of western U.S. was  formed, we knew it was formed from Sandstone that solidified somewhere between 1500-300 million years ago

As we discussed in the previous lecture, there are two main types of economic systems: a free market economy and a planned market economy. Before moving on to today's topic, I’ll recap the main point from last week.

In the free market economy, as I'm sure you recall, there's a limited public sector. The majority of all goods and services are produced by private companies with goal of making a profit. One advantage of this type economy is that companies will compete with each other and make the best possible products for the cheapest price. A disadvantage is that only products that will make a profit will be produced. Additionally, some service that everyone needs such as health education may be too expensive for everyone to afford.

In a planned economy, on the other hand, there is a limitted private sector. Most economic decisions are made by the governments. The government decides what will be produced and how much it will cost based on what they think are in the best interest of the people. An example of planned market is SS before 1899. One problem of this economy is that there is little incentive for firms to produce the best quality since they don't need to compete in the market.

Most countries of the world have elements of both types of economies. The balance between the two varies widely. In the United States, for example, almost all economic activity is run by private companies, with a very small proportion of activity, in areas such as Medicare and Socail Security, being founded by the government.

Now, to move on the main topic of today's lecture, what happens when an economy system switches over from a planned economy to a free market economy? What are the implications of the transaction? And how does it impact on labor, supply, demand and good services?

The steam engine was one of the most significant inventions of 19th century, especially when we consider how it impacted Western society which was particularly evident in two areas: transportation and manufacturing.

First, let's look at transportation. The steam engine enabled the development of steam trains and steam ships, until then communication had been slow-paced and  fairly leisurely. People depended on horses or ships. With the increases speed of travel, goods and materials such as wool or mental, could be transported to the world quickly, increasing output as a result.

Second, the stem engine had an enormous impact on manufacturing. In England and in the US, stem engines led to the construction of factories which increase the rate of production. Previously, clothing for example, were made by individual workers in their homes. With the construction of  factory, people began to leave home to town to work. It was the beginning of industry revolution that had a profound effect on economic and society and culture conditions all around the word.

Rising temperatures is causing a shift in the migration patterns of birds in North America, pushing them to migrate earlier in the year. This could endanger species that are not able to adapt successfully to the climate change. Recent research shows that birds accelerated their schedule by an average of 0.8 days per degree Celsius of temperature increase. Some studies suggest that changes in migration contribute to population decline, putting many species at risk of extinction.

We've been discussing how animals have adapted to the extreme conditions of living in the desert. Desert animals have developed a wide range of physical and behavioral mechanisms to survive the extremes of dryness and heat in the dessert. Some animals have developed special physiological structures to help them regulate body heat. Jackrabbits, for example, have large ears that allow air to cool their blood as it circulates. Other animals, develop behavioral adaptations, an example of behavioral adaptation is estivation. Well you probably know that bears go sleep during the coldest part of the winter, that's know as hibernation, well, in the desert, there are few types of animals, such as  the round-tailed ground squiirel that go to sleep during the hottest summer, and wake up when the temperature has gone down. This's know as  estivation。

This is one that I write follow reading:
Modern Surgery Technique
Surgery has traditionally been a medical practice that required invasive procedures to treat various illness and health conditions.
The benefits of moving diseased organs far outweighed the possibly harmful and traumatic effects of cutting into the human body. Modern surgery, however, has enabled the development of non-invasive and minimally surgical techniques that allow surgeons to operate while making minor or no incisions.
Non-invasive procedures refer to surgery techniques that do not require any incisions into the skin.
Minimally-invasive surgery refer to surgical techniques that requires only the small incisions into the skin.
The benefits of this approach for patients are numerous. Specially, these procedures result in few complications for the patients in terms of recovery. There is also a less likelihood of infection and less need for  antibiotics or other drugs. Recovery time is faster and therefor time spent in the hospital is shorter and considerably cheaper.
